These changes are primarily used for Undo/Redo, however there is no strict assumption about this internally, objects of these change types could also be used to perform more structured editing. (Note that these functions simply forward the change events to the childUDynamicMesh, which will post a mesh-change event that Apply a vertex deformation change to the mesh
